Application April 15, 1939, Serial No. 267,971 4 Claims. (01. 4 213 My invention relates to improvements in deodorizing apparatus.

One of the objects of my invention is the provision of novel means for removing contaminated air from a toilet bowl and discharging the removed contaminated air exteriorly.

A further object of my invention is the provision of novel means by which the contaminated air is discharged into a water sealed liquid discharge passage.

Another object of my invention is the provision of novel means for removing the contaminated air from the bowl, controlled by a movable seat above the bowl, the removing means being operated when the seat is in its operative position, and inactive when the seat is moved from said position.

Another object of my invention is the provision of novel means for conducting .the contaminated air from the bowl into its discharge passage, which conducting means includes a flushing conductor which discharges flushing liquid into the bowl.

Still another object of my invention is the provision of a novel apparatus 'of the kind described, which is simple, strong, durable, not likely to get out of order, and which is efficient in operation.

In the accompanying drawings, which illus trate the preferred embodiment of my invention,

Fig. 9 is a reduced under view of'the seat.

Fig. 10 is an enlarged top view of the inculation block of the circuit closer.

Fig. 11 is a diagrammatic view of the electric circuit which includes the electric motor that rotates the centrifugal blower.

Similar characters designate similar parts in the different views.

I designates the body of the toilet bowl, which is of substantially the usual form, having a usual inlet 2 for flushing liquid, as water, to which is connected one end of a rearwardly extending liquid conductor comprising a pipe" 3, the rear upwardly turned end of which supports a usual flushing tank 4.

The lower forward portion of the bowl I has a usual passage 5 for conveying the liquid and solid contents of the bowl to a sewer or cess pool, not shown. An apron 6 extends rearwardly and downwardly from the iront wall of the bowl I into the liquid 1 in the bowl below the liquid level, and over the intake end of the passage 5.

Extending upwardly from the top of thebowl near the rear end thereof are two eye bolts 8 in which is mounted a pintle 9 on which are pivoted two hinge leaves In and a hinge leaf II, the latter supporting a lid I2 adapted to rest on a seat I3 which is attached to the leaves I0. Two coil springs I4 on the pintle 9 have one set of ends bearing on the bowl I, and the other ends against the under side of the seat I3. These springs nor- I mally force the seat I3 to the raised position, shown in Fig. 1.

The parts just hereinbefore described comprise the usual toilet bowl apparatus.

For removing contaminated air from the toilet bowl I and discharging it into the passage 5, the following described mechanism is provided.

A circular housing I5, closed at its rear and having a central front opening, has extending from said central opening I6 a forwardly and downwardly projecting pipe extension H, 'the lower end of which is made integral with the upper side of the conductor 3 with which said extension interiorly communicates. In the lower portion of the pipe extension I! are downwardly and forwardly inclined baflles I8, which deflect downwardly out of the pipe extension I1, liquid passing through the conductor 3 to the bowl I.

From one sideof the circular housing I5 downwardly and forwardly projects a pipe extension I9, the forward end of which is connected by a coupling 2|] to a threaded pipe extension ZI of the bowl I, which is of metal, and which has a duct 22 communicating with the extension 2| and with the passage '5 under the apron 6.

The liquid inlet 2, serves as an outlet for contaminated air'in the bowl I, when the seat I3 is occupied and in its lower operative position, shown in Fig. 2. The outlet 2, conductor 3, pipe extension I'l, circular housing I5, pipe extension I9, pipe extension 2| and duct 22 serve as means for conducting the contaminated air from the bowl I into the discharge passage 5, through which it passes into a sewer or cess pool, not shown.

For propelling the contaminated air through said conducting means, air propelling means are provided, which, as shown, comprise the following described parts.

C'oncentrically rotatably mounted in the circular housing I5 is an air propelling device comprising a central hub 23 from which radially extend wings 24. The hub 23 is fastened rigidly to a horizontal shaft 25, the rear end of which is attached to and rotatable with the armature shaft 25 of an electric motor 21 having a supporting post 28, resting on the conductor 3, and clamped thereto by bolts 29 attached to a clamping plate 30, which bears against the under side of the conductor 3.

The electric motor 21 is in an electric circuit which includes a circuit closer carried by the seat l3, which controls the opening and closing of the circuit closer.

' Said circuit closer, as shown in Figs. 3 and 4, a base consisting of an insulating block 3| resting against the under side of the seat 13. A cup shaped cover 32 bears against the under side of theinsulation block 3|. Two screws 33 extend through the cover 32 and the block 31 into the seat l3, thus fastening the circuit closer to the under side of the seat I3.

The cover 32 is provided with a central opening through which extends a button 34 upon which rests the free end portion of a spring contact plate 35 fastened to the under side of the insulation block 3| by a screw 36.

When the seat I3 is depressed by an occupant to its lower operative position, shown in Fig. 2, the button 34 is forced by the bowl I upwardly until the spring contact plate 35 strikes a contact screw 31, which extends, as does the screw 36, through the insulation block 3 I.

In the under side of the seat 13 is provided a groove 38 in which is located a cable 39 containing two conducting wires 4|] and 4 I.

Referring to the circuit shown in Fig. 11, a current source is provided, which, as shown comprises the positive conductor 42 and the negative conductor 43 of a power or battery circuit.

The conductor 46 connected to the contact screw 31 is connected to the conductor 42. The conductor 4! is connected to the screw 36 and to one terminal of the motor 21, the other terminal of which is connected by a conductor 44 With the conductor 43.

When the seat 13 is depressed to its operative position, and presses the button so as to cause the button to force the contact plate 35 against the contact screw 31, the current will pass from conductor 42 through the conductor 40, contact screw 31, contact plate 35, screw 36, conductor 4|, motor 21, and conductor 44 to the negative conductor, thus causing the armature shaft 26 of the motor 21 to rotate, thereby rotating the air propelling device upon which the wings 24 thereof upon revolving will cause air to be forced from the bowl I through the air outlet 2, conductor 3, pipe extension 11, housing 15, pipe extension i9 and duct 22 into passage 5.

Upon the seat I3 rising, the contact plate 35 will leave the contact screw 31, thus breaking the circuit through the motor 21, which will stop rotating, as will the propelling wings 24.

By reason of the contaminated air being discharged from the bowl I into the passage 5, the

contaminated air will not enter the outer atmosphere.

By having the air propeller 24, and its housing [5 and the electric motor 21 mounted on the flushing pipe 3, outside of the bowl, many advantages accrue. A strong and durable structure is provided, that is easily and quickly applied to the bowl; that is readily accessible for repairs or replacement of parts; and with which the electric motor and its connections are free from liability to contact with water, used to flush the bowl, with resulting damage or inoperativeness.

By having the circuit closer, comprising the cover 32, contacts 35 and 31, and the operating button 34, assembled as a unitary structure carried wholly by the seat l3, it is easily and quickly afiixed in its operative position, where it is not exposed to liability of damage, and does not interfere with cleaning the upper edge of the bowl.

By having the motor 21 fastened to and carried by the flushing pipe 3, and the housing [5 fastened to the motor and having its air intake extension attached to and communicating interiorly with the flushing pipe 3; the air pipe discharge extension l9 carried by the housing, and the air propeller mounted in the housing 15 and operatively attached to the motor 21, these parts are united together to form an integral structure adapted for removal and replacement and for storage and transportation as a unit. Also by means of this construction, the flushing pipe 3 performs a triple function-that of conveying water to the bowl, that of conveying air from the bowl, and that of supporting the motor, fan and the fan housing.

Modifications of my invention, within the scope of the appended claims, may be made without departing from the spirit of my invention.
